[issue10574] email.header.decode_header fails if the string contains multiple directives
New submission from Roy H. Han starsareblueandfara...@gmail.com:
email.header.decode_header fails for the following message subject:
::
email.header.decode_header('=?UTF-8?B?MjAxMSBBVVRNIENBTEwgZm9yIE5PTUlO?==?UTF-8?B?QVRJT05TIG9mIFZQIGZvciBNZW1iZXJz?==?UTF-8?B?aGlw?=')
If the directives are removed and the padding problems are fixed, the subject
parses correctly.
::
email.header.decode_header('=?UTF-8?B?%s==?=' %
'=?UTF-8?B?MjAxMSBBVVRNIENBTEwgZm9yIE5PTUlO?==?UTF-8?B?QVRJT05TIG9mIFZQIGZvciBNZW1iZXJz?==?UTF-8?B?aGlw?='.replace('=?UTF-8?B?',
'').replace('?', '').replace('=', ''))

Re: Using xreadlines
Brett,
I'm not sure what exactly you're trying to do, but you can keep track
of line numbers using itertools.
import itertools
for lineIndex, line in itertools.izip(itertools.count(1), open('text.txt')):
print lineIndex, line
Here is sample code for breaking on a word and returning the previous line
def breakOnWord(filePath, word):
previousLine = ''
for line in open(filePath):
if word in line:
return previousLine
previousLine = line

You may have to do all things manually (tell, seek and looking for
newlines manually, iterating chars), that's why I have said it's not
handy. The other solutions are simpler.

Dear python-list,
I'm having some trouble decoding an email header using the standard
imaplib.IMAP4 class and email.message_from_string method.
In particular, email.message_from_string() does not seem to properly
decode unicode characters in the subject.
How do I decode unicode characters in the subject?
You don't. You can't. You decode str objects into unicode objects. You
encode unicode objects into str objects. If your input is not a str
object, you have a problem.
I can't speak for the OP, but I had a similar (and possibly
identical-in-intent) question. Suppose you have a Subject line that
looks like this:
Subject: 'u' Obselete type =?ISO-8859-1?Q?--_it_is_identical_?=
=?ISO-8859-1?Q?to_=27d=27=2E_=287=29?=
How do you get the email module to decode that into unicode? The same
question applies to the other header lines, and the answer is it isn't
easy, and I had to read and reread the docs and experiment for a while
to figure it out. I understand there's going to be a sprint on the
email module at pycon, maybe some of this will get improved then.
Here's the final version of my test program. The third to last line is
one I thought ought to work given that Header has a __unicode__ method.
The final line is the one that did work (note the kludge to turn None
into 'ascii'...IMO 'ascii' is what deocde_header _should_ be returning,
and this code shows why!)

Re: How do I decode unicode characters in the subject using email.message_from_string()?
Cool, it works!
Thanks, RDM, for stating the right approach.
Thanks, Steve, for teaching by example.
I wonder why the email.message_from_string() method doesn't call
email.header.decode_header() automatically.

It is interesting that decode_header does what I would consider to be
the right thing (from a pragmatic standpoint) with that particular bit
of Microsoft not-quite-standards-compliant brain-damage; but, removing
the tab is not in fact standards compliant if I'm reading the RFC

In particular, email.message_from_string() does not seem to properly decode unicode characters in the subject. How do I decode unicode characters in the subject? I read on the documentation that the email module supports RFC 2047. But is there a way to make imaplib.IMAP4 and email.message_from_string use this protocol? I'm using Python 2.5.2 on Fedora.

Re: % sign in python?
The percent sign is a placeholder.
For example, if
level = 1
msg = 'look'
Then
'[[Log level %d: %s]]' % ( level, msg )
becomes
'[[Log level 1: look]]'
%d means insert an integer
%s means insert a string
You can also use dictionaries.
d = {'string1': 'hey', 'string2': 'you'}
Then
'%(string1)s %(string2)s' % d
becomes 'hey you'

Is it possible to pass more than one argument to fget function?
I know: I can define a function with property name ('newfun' in the example)
and call it with more arguments. But then I do not get the benefits of
setter and property in general!

Re: Pythonwin
Hi Clive,
For ArcGIS, I use plain old VIM, IPython and IDLE.
If you really want PythonWin, then you can download Mark Hammond's Python
for Windows extensions: http://sourceforge.net/projects/pywin32/
Note also that with the pywin32 extensions, you can also use Python 2.5 to
access ArcGIS using
from win32com.client import Dispatch
arcgis = Dispatch('esriGeoprocessing.GpDispatch')
If you just need to access shapefiles, there is shapelib:
http://shapelib.maptools.org/
To make shapelib bindings for Python 2.5
1. Download *shapelib_1_2_10.zip *from http://dl.maptools.org/dl/shapelib/
2. Download *pyshapelib-0.3.zip* from
ftp://intevation.de/users/bh/pyshapelib
3. Extract *pyshapelib-0.3.zip*
4. Extract *shapelib_1_2_10.zip* to the folder containing pyshapelib.
Rename the extracted folder as *shapelib*
5. From the pyshapelib directory, run python setup.py build. The script
looks in its parent folder for the shapelib folder.
5. From the pyshapelib directory, python setup.py install
Hope that helps,
Roy

How do you install or launch pythonwin??
There is a distribution of PythonWin bundled with the
ArcGIS Desktop installation media, but it is not
installed by the ArcGIS installer.
You have three options:
1. Install it manually from the ArcGIS installation
media.
2. Find it on the web (google for it), download and
install.
3. (My recommendation) Don't bother. IDLE is pretty
good. Emacs even better (unless you hate emacs).
